Description

用于触摸敏感装置的框架及其工具
技术领域
本发明涉及一种用于触摸敏感装置的框架及其工具。
背景技术
触摸敏感系统(“触摸系统”)被广泛地用于各种应用中。通常，触摸系统被配置成检测与触摸表面直接接触或通过与触摸表面接近(即，不接触)的触摸对象，例如手指或触针。触摸系统可以用作膝上型计算机、设备控制面板中的触摸板，以及用作显示器(例如手持装置、例如移动电话)上的覆盖层。覆盖在显示器上或集成在显示器中的触摸面板也被称为“触摸屏”。许多其它应用在现有技术中是已知的。
存在许多用于提供触摸灵敏度的已知技术，例如通过将电阻线栅、电容传感器、应变仪等结合到触摸面板中。还存在各种类型的光学触摸系统，该光学触摸系统例如检测由触摸表面上或接近触摸表面的触摸对象所发射的光的衰减。
已知的触摸敏感设备是“表面上方的光学触摸系统”，该光学触摸系统具有一组光学发射器，该组光学发射器围绕触摸表面的周边布置，以发射在触摸表面上方传播的光。一组光检测器也围绕触摸表面的周边布置，以接收来自触摸表面上方的该组发射器的光。接触触摸表面的对象将衰减在光的一个或多个传播路径上的光，并引起由该检测器中的一个或多个检测器所接收的光的变化。对象的位置(坐标)、形状或面积可以通过分析在检测器处接收的光来确定。这种触摸系统的示例可以在例如PCT/SE2017/051233和PCT/EP2018/052757中找到。
触摸敏感装置的一个组件是用于将光正确地传播在触摸表面上的漫射器。漫射器可以是细长的塑料片，该塑料片的表面具有成角度的光漫射特性，以将发射的光漫射在触摸表面上。漫射器被夹持或胶合到触摸敏感装置的框架中。
漫射器组件的问题在于该漫射器组件的制造和安装相对昂贵。此外，漫射器必须被定位在触摸表面上方，以引导和漫射触摸表面上方的光。这意味着漫射器的尺寸影响触摸敏感装置的端部处的边框的尺寸。

具体实施方式
图1示出了包括细长框架102的触摸敏感装置100的横截面侧视图。细长框架102围绕触摸敏感装置100的周边延伸。细长框架102沿纵向轴线B-B延伸，该纵向轴线B-B延伸到如图1所示的页面中。在图3中示出了沿纵向轴线B-B延伸的细长框架102的一部分。图3示出了细长框架102的一部分的透视图。
细长框架102包括顶壁104、底壁106和连接在顶壁和底壁之间的侧壁108。细长框架102可包括限定用于固定内部组件的空隙的多个表面。实际上，细长框架102可包括任何合适的横截面形状以适应不同的组件和几何形状。例如，顶壁104、底壁106和侧壁108可包括多个外表面110。为了清楚起见，仅多个外表面110中的一个被标记。顶壁102、侧壁108和底壁106中的每一个可包括多个内表面和外表面。
图1示出了通过触摸敏感装置100的周边的一部分的横截面侧视图。为了清楚起见，未示出触摸敏感装置100的所有组件和结构。
光发射器组件112被安装在诸如印刷电路板(printed circuit board，PCB)的基底114上。为了清楚起见，未示出相互配合的(reciprocal)光检测器。然而，相互配合的光检测器组件被安装在与光发射器组件112相邻的基底114上。如前所述，光发射器组件和光检测器组件沿触摸敏感装置的周边布置在基底114上。
基底114通过第一安装件116固定到框架102。在一些实施例中，第一安装件包括至少一个基底安装槽116。基底安装槽116用于容纳基底114的边缘。以这种方式，基底114被滑动到基底安装槽116中，并且基底114在基底安装槽116中保持就位。在其它实施例中，第一安装件116可以是用于将基底114固定到框架102的螺钉、胶水或任何其它合适的固定装置。基底114被安装在框架102中，使得该基底在基本上垂直于触摸表面118的平面中延伸。以这种方式，触摸表面118在水平平面中延伸，并且基底114在顶壁104和底壁106之间的方向上延伸。在可替代的实施例中(未示出)，基底114可以在基本上平行于触摸表面118的平面的平面中延伸。
触摸表面118被安装在基底114上方或邻近基底114。在一些实施例中，触摸表面118在框架102中的第二安装件120中被安装到细长框架102。如图1所示，第二安装件120是一对垂直表面，接触表面118抵靠该垂直表面。
可替代地或另外地，第二安装件120是用于容纳触摸表面118的边缘122的周边触摸表面安装槽(未示出)。第二安装件120围绕触摸表面118的整个周边边缘122延伸。第一安装件116和第二安装件120均与框架102成一体。以这种方式，框架102可以使用包括第一安装件116和第二安装件120的横截面形状的模具来挤压。在一些可替代的实施例中，另外地或可替代地，第二安装件120可以是用于将触摸表面118固定到细长框架102的螺钉、胶水或任何其它合适的固定装置。
在一些实施例中，细长框架102包括至少两个分离的部分(未示出)。细长框架102的分离部分用螺钉、胶带或任何其它合适的紧固件紧固在一起。例如，光漫射器128被安装在细长框架102的一部分上，并且基底114被安装在细长框架128的另一部分上。
现在将参照图2更详细地讨论细长框架102。图2是图1所示的实施例的放大横截面侧视图。
光学组件安装槽124被定位在细长框架102的顶壁104和侧壁108的边角处。光学组件安装槽124的至少一部分被定位在第一安装件116和第二安装件120上方，该第一安装件和第二安装件用于分别固定至少一个光发射器112和触摸表面118。在一些实施例中，光学组件安装槽124的内表面126提供用于安装光学组件128的安装表面126。安装表面126是平坦的，当光漫射器128是柔性元件时，该安装表面在实施例中使光学组件128保持平坦。下文将进一步详细描述光学组件128。
在一些实施例中，光学组件可以是用于改变入射在光学组件上的发射的光的特性的光学组件。在这种情况下，光学组件能够以任何需要的方式会聚、发散、反射或折射入射光，或者过滤光或改变从发射器112发射的光的特性。在一些实施例中，光学组件128是光学膜。在一些实施例中，光学组件128是光漫射器128。在下文中，实施例将提及光漫射器128，但是在其它实施例中，光漫射器128可以用任何其它合适的用于改变入射在光学组件上的发射的光的特性的光学组件128代替。光学组件以与下文实施例中参照光漫射器128描述的相同的方式应用。
如图2所示，光学组件槽124或光漫射器安装槽124(如下文所述)是开口槽，该开口槽包括与细长框架102的内部空间134连通的开口132。光漫射器安装槽124在细长框架102的纵向轴线B-B上延伸。因此，当光漫射器安装在光漫射器安装槽124中时，光漫射器128与光发射器112和触摸表面118上方的位置成一直线，如图1中虚线箭头所示。可选地，安装表面126的宽度与开口132的宽度相同。
光漫射器安装槽124包括第一唇部136和第二唇部138，该第一唇部和第二唇部用于保持被插入到光漫射器安装槽124中的光漫射器128。以这种方式，第一唇部136和第二唇部138在光漫射器128的边缘上突出。
在一些实施例中，可选地，光漫射器安装槽124包括用于与光漫射器128接合的细长脊部140。因此，细长脊部140使光漫射器128推靠在第一唇部136和第二唇部138上。以这种方式，光漫射器128通过摩擦配合在光漫射器安装槽124中保持就位。这意味着安装表面126是细长脊部140的顶部上的表面。在其它实施例中，光漫射器安装槽124不包括细长脊部140，并且安装表面126是光漫射器安装槽124的平坦内表面。
可选地，细长脊部140推靠在光漫射器128上，以使光漫射器128变形(未示出)。可选地，细长脊部140推靠在光漫射器128上，以使光漫射器128具有凸形横截面形状。
可选地，细长脊部140和光漫射器128之间的摩擦力取决于用于光漫射器128和细长框架102以及例如细长脊部140的相关材料。
可选地，在一些实施例中，细长脊部140与光漫射器安装槽124的开口132相对地对准。由于细长框架102通过模具挤压，则特征的最小深度大约为1mm。这意味着当挤压细长框架102时，光漫射器安装槽124不能小于1mm窄。因此，通过提供与开口132相对并朝向和/或伸向开口132突出的细长脊部140，具有小于1mm的厚度的光漫射器128可保持在细长脊部140与第一唇部136和第二唇部138之间。如图9所示，在一些实施例中，在垂直于安装表面126的方向上，细长脊部140与第一唇部136或第二唇部138之间的间隔D小于1mm。在一些实施例中，间隔D等于或小于光漫射膜128的厚度。例如，根据光漫射膜128是否包括背衬层，间隔D等于或小于0.3mm或0.2mm。在一些实施例中，细长脊部140从开口132延伸出超过第一唇部136和第二唇部138。因此，如果光漫射器128是柔性膜128，则光漫射膜128将围绕细长脊部140以及第一唇部136和第二唇部138弯曲，如图9所示。这意味着当光漫射膜安装在光漫射器安装槽124中时，光漫射膜128将保持凸形形状。
在其它实施例中，不需要细长脊部140，例如光漫射器128具有的厚度大于1mm或不是柔性膜。
另外，可以有多个细长脊部(未示出)，以用于将光漫射器128推靠在第一唇部136和第二唇部138上。
在其它实施例中，安装表面126可以是插入到光漫射器安装槽124中的分离组件(未示出)。以这种方式，安装表面元件与光漫射器128一起插入到光漫射器安装槽124中。
有利地，通过提供作为框架102的一部分的整体式安装表面126，减小了触摸敏感装置100的边框130突出在触摸表面118上方的高度H。这是因为不需要体积大的、分离的漫射组件被固定到细长框架102。
光漫射器安装槽124与光发射器112对准，以用于接收和漫射触摸表面118上的光。以这种方式，从光发射器组件112发射的光入射在光漫射器128上。
为了促进光在触摸表面118上的有效漫射，光漫射器安装槽124和光漫射器128相对于触摸表面118的平面A-A成角度。在一些实施例中，光漫射器安装槽124和/或光漫射器128相对于触摸表面118的平面A-A的角度介于40到60度之间。
在一些实施例中，光漫射器安装槽124和/或光漫射器128相对于触摸表面118的平面A-A的角度是45度。在其它实施例中，角度可以根据光漫射器128的表面的漫射特性(例如，几何形状、材料、表面图案)而变化。在一些实施例中，光漫射器128包括光漫射表面，该光漫射表面将入射的发射光漫射穿过触摸表面118。
在一些实施例中，光漫射器128是具有光漫射材料的柔性细长条。在一些实施例中，光漫射材料是光漫射膜128。可选地，光漫射膜128包括用于将光漫射膜128粘附到安装表面126的粘合剂背衬(未示出)。在一些实施例中，新的、未使用的光漫射膜128包括背衬衬垫，该背衬衬垫用于覆盖粘合剂背衬，直到光漫射膜128施加到安装表面126。可选地，由于光漫射膜128在细长脊部140与第一唇部136和第二唇部138之间的槽中保持就位，则光漫射膜可以被安装在光漫射器安装槽124中同时仍包括背衬衬垫。
在一些实施例中，光漫射膜128不包括背衬衬垫。在这种情况下，光漫射膜128包括在压力下被激活的触觉粘合剂。这意味着光漫射膜128在存储时不会粘附到其自身。在其它实施例中，光漫射膜128不包括粘合剂背衬。在这种情况下，在光漫射膜128被安装在安装表面126上之前，该粘合剂被施加到安装表面126。
在一些实施例中，光漫射膜128的宽度为3.30mm。在一些实施例中，光漫射膜128的宽度与安装表面126(未示出)的宽度相同。在其它实施例中，光漫射膜128的宽度大于细长脊部140上的安装表面126的宽度。实际上，通过提供光漫射膜的宽度大于细长脊部140的宽度，光漫射膜128的边缘由第一唇部136和第二唇部138(可选地在没有粘合剂的情况下)保持就位。
在一些实施例中，光漫射器安装槽124的宽度比光漫射膜128的宽度略宽，以便光漫射膜128可以自由地供送(fed)到光漫射器安装槽124中。
以这种方式，当光漫射膜128被施加到安装表面126时，光漫射膜128覆盖由槽开口132暴露的光漫射器安装槽124的至少一部分。
具有背衬衬垫的光漫射膜128的厚度大约为0.30mm。没有背衬衬垫的光漫射膜128的厚度大约为0.20mm，并且背衬衬垫的厚度大约为0.1mm。在其它实施例中，光漫射膜128的宽度和厚度是变化的。光漫射膜128是柔性的并且可存储在辊中。这意味着光漫射膜128的长度可以是任何合适的长度以匹配细长框架102的长度。有利地，这意味着光漫射膜128可以被分配和用刀切割以匹配细长框架102的长度。
现在将参照图4至图8描述将光漫射器128施加到细长框架102。图4至图8示出了细长框架和用于将光漫射器128施加到细长框架102的工具400的透视图。
转至图4，现在将进一步详细地描述用于将光漫射器128施加到细长框架102的光漫射器施加工具400。为了清楚起见，如图4所示的工具400未示出细长框架102。然而，图5和图6示出了安装在工具400中的细长框架102。
工具400包括能够与细长框架102接合的夹具402。夹具402包括用于将细长框架102对准在预定位置的至少一个参考表面404。在一些实施例中，夹具402包括用于与顶壁104的外表面和侧壁106的外表面接合的第一参考表面404和第二参考表面406。以这种方式，由顶壁104的表面和侧壁106的表面限定的顶点200与由第一参考表面404和第二参考表面406限定的相互配合的(reciprocal)顶点408对准。
当如图4所示的夹具402使用顶点200和408以将细长框架102对准在夹具402中时，细长框架102上的任何表面可以用于定位夹具402的参考表面。实际上，夹具402可以是与细长框架102相互配合(reciprocal)的任何合适的形状或尺寸。如图4所示的夹具402的长度与如图3所示的细长框架102的长度相互配合(reciprocal)。因此，夹具402可以是任何合适的长度以适应细长框架102的长度。
工具400包括用于接收光漫射器128的光漫射器供送器(feeder)410。光漫射器供送器410包括供送表面412，该供送表面用于相对于夹具402定位和对准光漫射器128。从图4可以看出，光漫射器128被定位在供送表面412上。光漫射器供送器410包括具有通道壁416、418的通道414，该通道用于限制光漫射器128在供送表面412上的从一侧到另一侧的位置。通道414变窄至供送口420。供送口420被配置成接收光漫射器128并将光漫射器128定位在从一侧到另一侧的方向上。供送口420包括桥接部分422，该桥接部分用于防止光漫射器128在垂直方向上移动。
转至图5，细长框架102安装在夹具402中。细长框架102已经被倒置，使得顶点200被插入夹具402中。因此，顶壁104和侧壁106与第一参考表面404和第二参考表面406接合。当细长框架102接合夹具402时，光漫射器安装槽124与供送口420对准。在一些实施例中，供送表面412与光漫射器安装槽124在同一平面内。这意味着当光漫射器128沿图4所示的箭头方向被供送到供送口420时，光漫射器128被推入光漫射器安装槽124中。
可选地，细长框架102被夹紧到夹具402，使得在将光漫射器128施加到细长框架102的过程中，细长框架102相对于夹具402固定。
在一些实施例中，然后用户用他们的手指手动推动光漫射器128。以这种方式，用户将光漫射器128供送(feed)到光漫射器安装槽124中。
夹具402和光漫射器供送器410在图4和图5中示出为分离的元件。夹具和光漫射器供送器410相对于彼此固定，使得供送表面412相对于第一参考表面404和第二参考表面406定位。
在一些实施例中，夹具402和光漫射器供送器410是一体的并且是单个元件。在其它实施例中，光漫射器供送器410和夹具402是可分离的。因此，不同的光漫射器供送器410可与其它夹具402互换。这意味着夹具402和光漫射器供送器410可以被配置成用于不同尺寸和形状的光漫射器128和不同尺寸、形状和取向的细长框架102。
转至图6，现在将描述另一个实施例。图6示出了安装在用于施加光漫射器128的光漫射器施加工具400中的细长框架102的透视图。图6与图5所示的实施例相同，除了光漫射器供送器410包括用于将光漫射器128供送到光漫射器安装槽124中的供送机构600。
供送机构600包括第一辊602和第二辊604。第一辊602和第二辊604可旋转地安装在光漫射器供送器410上。为了清楚起见，未示出用于第一辊602和第二辊604的安装框架。第一辊602和第二辊604中的一个或两个安装在电马达(未示出)的驱动轴上。
第一辊602安装在供送表面412的上方，并且第二辊604安装在供送表面412的下方。在一些实施例中，滚动表面606、608与供送表面412相交。以这种方式，当光漫射器128插入第一辊602和第二辊604之间时，第一辊602和第二辊604接合光漫射器128的顶表面和底表面，并且光漫射器128被辊602、604推向夹具402。然后，光漫射器128被供送到光漫射器安装槽124中。
在另一个实施例中，仅一个辊602用于将光漫射器128推向光漫射器安装槽124中。例如，仅提供了安装在供送表面412上方的第一辊602。
一个或两个辊602、604夹持光漫射器128的表面并将光漫射器128推入光漫射器安装槽124中。在一些实施例中，辊602、604的摩擦系数高于细长框架102的表面的摩擦系数。因此，当光漫射器128被供送到光漫射器安装槽124中时，辊602、604可以继续推动光漫射器128一直穿过光漫射器安装槽124。
在其它实施例中，供送机构600可以是用于将光漫射器128推入光漫射器安装槽124中的任何其它合适的机构。例如，供送机构600可以包括安装在往复连杆(未示出)的端部处的橡胶止挡件，该橡胶止挡件将光漫射器128逐步推入光漫射器安装槽124中。
现在将参照图7描述另一个实施例。图7示出了用于将光漫射器128供送到光漫射器安装槽124中的另一个光漫射器施加工具700。工具700被布置成相对于细长框架102移动，并通过将光漫射器128拉动穿过光漫射器安装槽124而将光漫射器128供送到光漫射器安装槽124中。
工具700包括具有第一突出臂712和第二突出臂714的主体710。第一突出臂712包括用于接合细长框架102的侧面704的第一参考表面702。第二突出臂714包括用于接合细长框架的顶壁104的第二参考表面706。当工具700相对于细长框架102移动时，第一参考表面702和第二参考表面706保持工具700相对于光漫射器安装槽124的相对位置。在一些实施例中，第一参考表面702和第二参考表面706在正交平面中，以仅沿细长框架102的纵向轴线B-B限制工具700相对于细长框架102的相对运动。
工具700被布置成在平行于如图3所示的细长框架102的纵向轴线B-B的方向上移动。
工具700的主体710包括从主体710突出的光漫射器供送臂708。光漫射器供送臂708被配置成突出到细长框架102的内部空间134中并突出到光漫射器安装槽124中。光漫射器供送臂708包括夹持器716，该夹持器将光漫射器128的端部夹持到光漫射器供送臂708。在一些实施例中，夹持器716是双面粘合剂或软垫圈。可替代地，夹持器716是用于将光漫射器供送臂708固定到光漫射器128的紧固件，该紧固件例如夹子、夹钳、螺钉、销、眼、胶水或任何其它合适的装置。
以这种方式，当工具700相对于细长框架102移动时，光漫射器128也相对于细长框架102移动。以这种方式，一旦光漫射器供送臂708被固定到光漫射器128的端部，则工具700被旋入细长框架102的一个端部。同时，光漫射器128被手动供送到光漫射器安装槽124中约10mm。然后，工具700沿细长框架102的纵向轴线B-B滑动，并且光漫射器128被拉动穿过光漫射器安装槽124并被供送到光漫射器安装槽124中。
在一些可替代的实施例中，工具700可以被固定并且细长框架102相对于工具700移动。
现在将参照图8描述另一个光漫射器施加工具800。图8示出了具有光漫射器施加工具800的细长框架102的透视图。细长框架102与参照先前实施例所讨论的细长框架相同。
光漫射器施加工具800包括被安装到光漫射器128的端部的光漫射器供送臂802。光漫射器供送臂802包括用于与细长框架102的一个或多个内表面806接合的参考表面804。以这种方式，光漫射器供送臂802还包括参考表面804。光漫射器128被手动插入到光漫射器安装槽124中约10mm。然后，光漫射器供送臂802从用户可以夹持并拉动的内部空间134突出。然后，如参照图7所示的实施例所描述的，光漫射器128被拉动穿过光漫射器安装槽124。
在一些实施例中，光漫射器供送臂802用粘合剂紧固到光漫射器128。在其它实施例中，光漫射器供送臂802用任何合适的装置紧固到光漫射器128，该任何合适的装置例如夹子、夹钳、螺钉、销、眼、胶水等。
在一些实施例中，光漫射器供送臂802可以是刚性的或柔性的。例如，光漫射器128被固定到用于将光漫射器128拉动穿过光漫射器安装槽124的拉片或螺纹。
在另一个实施例中，组合了两个或更多个实施例。一个实施例的特征可以与其它实施例的特征组合。
已经特别参照所示出的示例讨论了本发明的实施例。然而，应当理解，可以在本发明的范围内对所描述的示例进行变化和修改。
